PAPER RECEPTACLE.

Specification of Letters Patent.

Patented Aug. 6, 1918.

To all whom it may concern:

Be it known that I, CoLMAN J. MULLIN, a citizen of the United States, residing at Locust, county of Monmouth, and State of New Jersey, have invented a certain new and useful Paper Receptacle, of which the following is a specification.

This invention is a paper receptacle or container and the object of the invention is.

Speaking generally, the container is constructed from a single blank a portion of one edge of which is provided with serrations or extensions, which blank is adapted to be wound on a mandrel to form the body of the container, and simultaneous therewith the serrations or projections are infolded to form the bottom of the container.

It will be understood that the container may be composed of as many plies of "material as desired, depending on the size and strength desired, and that one or more layers of waterproof material, 6. g., impervious fabric may be interposed between said plies.

As will appear from the hereinafter detailed description, an important feature of the invention consists of a one piece container wherein the bottom thereof is en ported by the body of the container, an above the lower edge thereof.

Another feature of the invention consists in the novel construction of the cover, and the manner in which it is secured in place on the body.

Features of the invention other than those specified will be apparent from the following description read in conjunction with the accompanying drawings.

In the accompanying drawings, I have illustrated one practical embodiment of the invention, but the construction shown therein is to be understood as illustrative, only, and not as defining the limits of the invention.

Figure 1 shows a receptacle constructed according to the present invention, said view illustrating the receptacle partly in section and partly in elevation.

Fig. 2 is a bottom plan view of the receptacle shown in Fig. 1.

Fig. 3 shows, on a greatly reduced scale, a portion of the blank from which the receptacle of the present invention may be constructed.

Referring to the drawings, and more particularly Fig. 3, I have illustrated the blank, A, from which a receptacle embodying the present invention may be constructed. For clearness and simplicity of description I have divided this blank, by means of the dot and dash lines, a, into a plurality of sections, I, II, III and IV. As will be more clearly stated hereinafter, this blank is not composed of these four sections only, but sections shown forming the first cycle of the construction of the receptacle of usual size and strength. If, however, an increased strength is desired, the blank may continue to include several more sections which would be very similar, in their contour, to the sections illustrated.

It will be noted that section I is practically uninterrupted alon its bottom edge, but sections II, III, and 1%: are provided with projections of varying shapes and sizes, according to the sections in which they are positioned.

Having described the blank from which the receptacle is formed, the manner in which it is manipulated will next be set forth.

The blank, A, is wound upon a mandrel, the section, I, being long enough to extend at least once around said mandrel, and this first winding of the section, I, forms an inner ply of the material forming the body of the receptacle. The blank, A, is provided on its surfaces with a. suitable adhesive so that when portions thereof are brought together, they will be adhesively re tained in position. The operation of winding continues and the section II is wound.

Simultaneously with the winding of section II, the projections, 2, formed on the lower edge of the blank, are turned in and folded on the dotted lines, a, a and these projections, 2, are of such length that they will reach to the center of the receptacle. Thus when the winding of the second section is completed, the bottom of the receptacle will be substantially closed by the projections, 2.

The third section, section III, is next wound, and the projections, 3, formed thereon are simultaneously inturned. jections, 3, are of such length that they overlap the bottom edge of the receptacle, thus far formed, so that their free edges abut the bottom formed by infolding the rojections, 2. Thus an annular ring is ormed around the receptacle, and beneath the interior layer of the bottom, so that the weight of the material carried therein will be sustained on the vertical portion of the projections, 2, 3, etc.

Section IV is next wound, and the projections, 4, are infolded after the manner of procedure set forth in connection with section II, with the exception that the projections, 4, are so arranged on a blank relative to the projections, 2, that they will be staggered with relation thereto so that the joints between the projections, 2, will be closed by the projections, 4, and vice versa. Moreover, the projections, 4, are somewhat longer than the projections, 2, and are thus adapted to overlap the center of the receptacle and effectually render the same impervious at that joint.

The foregoing manner of constructing my improved receptacle accomplishes a one-piece container which, in many cases, will be adequately strong and impervious for commercial uses, yet I prefer to provide additional features which greatly enhance the strength, imperviousness, and lasting qualities of the receptacle. After the container has been formed in the manner specified, I preferably emboss a ring or form a recess, Z), in the center of the bottom, as shown in Fig. 1. This operation will cause a portion of the receptacle bottom to be in relief from the remainder of said bottom, whereby the bottom of the receptacle, is drawn taut. This operation draws the projections, 24, tightly together and takes up any slack which may be occasioned during the making, and the bottom is thus rendered taut and rigid. Although it is not essential I preferably finish the winding of the body of the receptacle with 'a section, V, similar to section, I, 2'. e., a section devoid of projections along its bottom edge. This gives a finished appearance to the receptacle and covers the ends of the slits between the projections of the other series. The annular bead, B, is next formed in the receptacle at a point just below the bottom, and simultaneously with the forming of the bead that portion of the body intermediate the bead and the bottom is corrugated vertically, which operations The progreatly strengthen the receptacle, and imparts rigidity and stiffness thereto.

In some forms of receptacle I find it advantageous to interpose a layer of fabric, G, properly treated to render it impervious and rigid, between the plies of the body during the winding of the blank. I have shown this fabric as interposed between the plies of the body of the container only, but it will be understood that if so desired, this fabric may be provided with suitable projections along its bottom edges which projections may be infolded between the plies of the bottom.

Another feature which I may employ in some forms of container is the provision of an air space, d, intermediate to two or more of the plies. In which case the adjacent plies of the body are held in spaced relation by means of filler strips, D, extendin annularly between said plies at the top an bottom of the receptacle.

In certain forms of containers, 6. 9., those adapted for the reception of lard, etc., it is preferable that a suitable bail or handle, E, be provided, and I have, accordingly, embodied improved means in my invention for allowing of this. When a bail is desired, retaining pieces 6, preferably in the form of a shell having an annular flange, are built in the wall of thereceptacle. The retaining pieces, 6, are ositioned so that the flanges thereof are built in between the plies of the receptacle body, and such plies as are wound after the insertion of the members, 12, are provided with apertures, 0, so as to allow the members, 6, to project out through the side of the receptacle for the reception of the ends of the bail.

The foregoing description sets forth in detail the form of my invention embodying a certain number of plies, but it will be manifest that the number of plies may be varied according to the size and strength of the container required. If the number of plies are increased, section similar to I to IV, inclusive, are duplicated to form a bottom of increased thickness and consequent strength.

The top of the receptacle may be provided with a cover of any form or type, but I prefer to use the form illustrated in Fig. 1 of the drawings. This cover, F, embodies a disk having a peripheral, U shaped, member which, when the cover is in position on the receptacle, straddles the upper edge of the body thereof. The wall of the receptacle is provided with an annular bead, G, and the cover, F. is provided with complementary beads, H, H, which cooperate with the bead, G, on the exterior and interior of the wall of the receptacle, respectively. Portions of the cover which engage the walls of the receptacle, are preferably coated with an adhesive so that after the cover has been sprung into place, the adhesive and cooper ating beads ma1nta1n' the cover against displacement and form an impervious olnt.

A receptacle of the present invention is 5 neat. in appearance, strong, and durable,

and embodies many novel features. It will be understood that some of these features may be utilized in the manufacture of the easily and cheaply manufactured, and when placed upon the container forms a thoroughly impervious cover therefor. The cover, F; I have shown in the drawings as stamped from a blank embodying one thick ply of material. I wish it to be understood, however, that if desired, I may construct the closure in the manner in which the receptacle itself is formed.

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is 1.
